How to detect if users stop typing in EditText android

There is a very simple and easy way of doing this using RxBindings for Android,

Get the library if you haven't already,

compile 'com.jakewharton.rxbinding:rxbinding:0.4.0'

Add and modify this snippet to your needs,

RxTextView.textChanges(mEditText)
            .debounce(3, TimeUnit.SECONDS)
            .subscribe(textChanged -> {
                Log.d("TAG", "Stopped typing!");
            });

What is Debounce Operator? - Learn more about it here

In our context, debounce will only notify you of the text change inside the EditText after a certain time has passed from the last text change that occurred inside the EditText.

Here I am waiting for 3 seconds until the last text change happened to conclude that the user has stopped typing. You can modify it according to your needs.

This is how I did and works for me!

long delay = 1000; // 1 seconds after user stops typing
long last_text_edit = 0;
Handler handler = new Handler();

private Runnable input_finish_checker = new Runnable() {
    public void run() {
        if (System.currentTimeMillis() > (last_text_edit + delay - 500)) {
            // TODO: do what you need here
            // ............
            // ............
            DoStuff();
        }
    }
};

EditText editText = (EditText) findViewById(R.id.editTextStopId);
editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged (CharSequence s,int start, int count,
    int after){
    }
    @Override
    public void onTextChanged ( final CharSequence s, int start, int before,
    int count){
        //You need to remove this to run only once
        handler.removeCallbacks(input_finish_checker);

    }
    @Override
    public void afterTextChanged ( final Editable s){
        //avoid triggering event when text is empty
        if (s.length() > 0) {
            last_text_edit = System.currentTimeMillis();
            handler.postDelayed(input_finish_checker, delay);
        } else {

        }
    }
}

);
